Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used, for example, in confectionery manufacturers as a proofing machine for aging bread dough or the like before baking, or in cooked dishes at a ryokan or Japanese restaurant. It relates to a storage room for heating and keeping foods used as a greenhouse for stocking.

[0002]

2. Description of the Related Art Bread is produced by adding yeast to wheat flour,
A mixing process of adding sugar, salt, etc. and kneading with water,
The mixed dough is divided into a finishing process of dividing and rolling, a proofing process of heating in a second aging furnace (called a proofing furnace) to complete aging, and a final baking process. In aging, aging is performed by heating and humidifying.

[0003] A conventional proofer is a box body in which shelves are arranged in a row on the left and right, in which boxes for arranging dough such as bread are put in a shelf shape. Has
A heater that raises the temperature inside the box and a humidifier that raises the humidity were installed inside, and nichrome wire was used for the heater. Further, as the humidifier, one having a heater using a nichrome wire for heating the water in a water reservoir was used.

[0004]

According to the conventional storage container for heating and warming foods as a proofer, since the heater is installed only at the bottom and under the floor plate, the temperature inside the proofer increases. Is slow, aging of dough such as bread takes time, and since the temperature is inevitably high on the upper shelf and decreases toward the bottom, the degree of aging of the dough varies and the quality is There was a problem of non-uniformity.

As for the humidifier, since the heater is provided under the water reservoir, it is apt to malfunction due to the influence of water, which often causes malfunction, and the water reservoir cannot be easily removed. Since it was built in, there was a problem that it became unsanitary because it was difficult to clean. In addition, there is a problem that complicated piping work is required.

The present invention has been made in view of the above circumstances.
Not only can food be warmed and warmed rapidly, but it can also be heated uniformly, and can be used hygienically, providing a storage room for warming and warming food that does not require troublesome piping work. Aimed at.

[0007]

In order to achieve the above object, the present invention relates to a box body having an open front surface capable of storing food, at least a bottom wall, left and right side walls, and a back wall. The panel heater was built in as a whole, and the panel heater was mainly made of a high-foamed resin heat insulating plate, and a planar heating element made of carbon fiber was sandwiched inside the heat insulating plate to form a reinforced insulating layer of low foamed resin. A storage structure for heating and keeping food with a sandwich structure was constructed.

[0008] Further, shelves are arranged in a row inside the box,
A panel heater that heats from the top and bottom may be hooked on the shelf receiver. Further, a hot water container which can be heated by the panel heater may be provided on the bottom wall so as to be able to be taken in and out. Furthermore, a refrigerating device may be provided on the top of the box.

[0009]

[Function] Since the inside of the box is heated not only at the bottom but also at both sides and the back, a uniform internal temperature can be obtained, so that the food can be evenly warmed or kept warm. Due to the large amount of far infrared rays generated by the sheet-shaped heating element made of a material, the effect of heating the far infrared rays is expected.

It is known that far infrared rays have the effect that the heat easily penetrates into foods, rapidly heats them up to the core, has a deodorizing effect, and has an aging effect on foods. Moreover, in order to accelerate the thawing, it can be effectively used as a thawing device depending on the food material. Furthermore, if it is possible to hang a shelf-shaped heater that heats from the top and bottom on the shelf receivers lined up inside,
Various foods placed on each shelf heater can be warmed evenly from the surroundings and kept warm.

In this case, the bottom wall 15, The panel heater 14 is used not only on the left and right side walls 17 and 17 and the back wall 19 but also on the upper wall 20 and the shelf wall 22, which are covered with the skin layer 24. The skin layer 24 may be a stainless plate, a resin sheet, a coating film, or the like.

[0022]

As described above, according to the present invention, there are the following excellent effects.

The inside of the box body is heated not only by the bottom wall but also by the left and right side walls and the back wall, and since the heating is done by the panel heater of the planar heating element, the internal temperature becomes uniform, The food can be heated or kept uniform.

The panel heater is mainly composed of a heat insulating plate body having a high heat insulating property of a high foaming resin, and a planar heating element is sandwiched inside the heat insulating plate body, and a reinforcing insulating layer of a low foaming resin having a relatively good heat conduction. Has a sandwich structure with good heat conduction efficiency to the inside, and since the planar heating element is made of carbon fiber that generates a large amount of far infrared rays, With the addition of a osmotic effect, heating is quickly and efficiently, and it is suitable for energy saving.

Since a large amount of far-infrared rays is generated from the sheet heating element, it is possible to accelerate the ripening of the food or to make the taste mellow and to expect a deodorizing effect. It can also be used efficiently for thawing.

Since shelf-like heaters for heating from the upper and lower surfaces are hooked on the shelf receivers arranged inside the box (claim 2), the food on the shelf is uniformly heated from the surroundings. , Has a better heat retention effect.

Since it is possible to perform humidification simply by placing the hot-water container on the bottom wall without the need for a conventional humidifier composed of a water reservoir equipped with a heater, which is difficult to clean up,
Inconvenience such as failure of the humidifying device can be eliminated, and the water in the hot water container can be replaced for hygienic management (claim 3).

If a refrigerating device is provided on the upper part, "freezing"
→ The process of "thawing" → "fermentation" can be taken, and various uses are possible.
